PETROLEUM-OIL BURNER.

SPECIFICATION forming part of Letters Patent N 0. 719,762, dated February 3, 1903.

Application filed May 13,1902. Serial No. 107,074. (No model.)

To all whom it may concern.-

Be it known that LALEXANDERF. DEMORY,

- of Nacogdoches,in the county of Nacogdoches and State of Texas, have invented anew and useful Improvement in Petroleum-Oil Burners, of which the following is a specification.

My invention is in the nature of a novel construction and arrangement of burner for utilizing crude petroleum for the purpose of furnishing heat, power, and light for the use of heating and cooking stoves, bake-ovens, furnaces for hot air, steam, or water, the boilers o1": locomotives and ships, and various other uses for which it may be applicable.

It consists in a comparatively small and simple burner which is easily portable and which, with various accessories for regulating the supply and discharge, operates upon the principle of generating steam in one chamber and then passingit to another, in which it is superheated, and thence into another chamber, to which the oil is fed and in which the steam and heated oil are mixed and heated to form a combustible gas,which then issuing through nozzles under the steam-pressure is immediately ignited and burned to furnish heat for any of the purposes named and at the same time the necessary heat to continue the operation by generating more steam and heat fresh accessions of oil in a continuous manner. Traps are employed to control the water-level and to give relief also as against explosion and for the removal of surplus water and gas, separating the water and sending it to the sewer, and saving the gas in a gasometor for lighting purposes, the oil-tank to be placed underground or at any suitable low level and to be fed by hydraulic pressure, all as hereinafter more fully described with reference to the drawings, in which- Figure 1 is a side elevation of my burner shown applied to the supply pipe tanks, valves, traps, and other accessories of my system; and Figs. 2 to 11 are details.

The burner proper, which is to be inserted in the fire-box of a furnace or at other point of utilization, consists of the cast-iron chamber B, in which steam is generated and which I term the primary steam chamber, a second cast-iron chamber B, in which the steam is superheated, an intermediate castiron chamber E, in which the steam and oil are mixed, nozzles F F, from which the combustible gas issues and is burned, and a guard plate or hood G to protect the mixer against the excessive heat of the blast in the fire-box. (Not shown.) The chambers above named are connected by pipes, as shown, and the jets of burning gas issuing from the nozzles F F are directed outwardly on both sides of the mixer against the steam-chambers B and B and also upwardly against the pipes and mixer-chamber.

A is a water-supply pipe to chamber B, where water is converted into steam, which passes through pipe 0 into superheatingchamber B and on through pipe 0 into oilmixing chamber E.

D is an oil-supply pipe extending to mixing chamber E where the oil is converted into gas and forced out through the nozzles F F with the steam coming from the pipes O 0 forming a combustible gas which is burned and the blaze heating chambers B B converts the fresh accessions'of water into steam. In Fig. 9, 7 shows the angle of top hole in each nozzle F, which holes throw the blaze upward, while holes at S throw the blaze against chambers B B. These nozzles are also made with only one hole in each, directed upwardly somewhat, as seen in Fig. 10. The supply of water, steam, and oil to chambers B and E is controlled by valves 9 and 10, which regulate the proper amount of water and oil by the use of grooved cone-pulleys (see Figs. 5 and 6) and a belt of Wire cable or cord 6, passing around same, as shown in Fig 1, or by means of gear-wheels, as shown in Fig. 11, as may be required.

H is a gas and safety and overflow pipe, which is connected to chamber B, as shown in Figs. 1 and 2. The pipe H is to enter chamber B at any point desired in a manner so that the water passing through A into chamber B will fill the chamber B to thedepth of about three-eighths of an inch or more, as may be required,and then flow out through the pipe H. For this purpose a nipple, as

shown at 26, in the pipe-fitting (see Fig. 2) has a small hole in the side next to the burner and at the bottom side of pipe through which the water from pipe A passes into chamber B, and when the water is about three-eighths of an inch deep or more it will flow back out over the top end of nipple 26 and out through pipe H. Instead of this arrangement of nipple 26 the water-pipe A and the outflow-pipe H may have separate connections with the chamber B at diiferent levels, as seen in Figs. 3 and 4. Pipe H is used to convey water and gas not consumed in the burner into a trap-chamber K, Fig. 1, and the end of pipe H being submerged in water the gas will rise through the water and pass out through stand-pipe M into a gasometer X or storage-tank for gas, and the surplus or overflow of water will pass out through iron pipe L into the sewer s or onto the ground, as may be required.

The pressure in the burner is regulated by means of the traps K and L, which will prevent an explosion in the burner and also regulate the fire.

' O is an oil-tank, showing at S a valved inlet for filling the tank with oil.

W is a water-tank placed above the level of the burner.

Q is a water-pipe through which water passes into the bottom of tank O,and the pressure of this water forces the oil out through pipe D into chamber E. ater-pipe Ais connected with water-pipe Q from tank IV and conveys water into chamber B. When the oil-tank is to be filled, a valve 20 in the waterpipe Q will be closed and a valve R is opened, through which the Water from oil-tank 0 will flow out onto the ground or into sewer as the oil enters at S.

U is a float to which wire 00 is attached, which passes up through pipe T to the top end. The float U will float in water and sink in oil, and as the oil is consumed the water raises the fioat,andthe wireextendingthrough pipe T will indicate the amount of oil in tank.

N represents the water-line in the tank 0 and showing the position of the float between the water and oil.

V is a drain-valve near the top of oil-tank, and Y is a glass gage to be used to ascertain when the oil is above the points where they are placed in the side of the tank.

' Mixing-chamber E may have a pipe connection on top, or it can be near the top on the side for connecting with a pipe to convey gas out into the pipe H. By thus connecting such outlet-pipe to pipe H, as shown in dotted lines at 15 ,\or at any convenient point the gas may be conveyed directly into trapchamber K. The chambers B B have lugs on their bottom sides, which are fitted into notches in the end of a pan J to hold the same in place.

The mixingchamber E has an opening or hole between the nozzles F F, covered or stopped with a plug or cap I. The cap I is for the purpose of uncovering this hole if at any time it is necessary to clean the inside of chamber E. 12 is a screw-bolt for fastening cap I to chamber E, as seen in Figs. 7 and 8.

13 shows a flanged clamp for holding the cap closed to make a tight joint.

14: is a projection on the surface of the cap for the purpose of pushing or knocking same from over the hole in chamber E.

G G is a housing or covering for chamber E, which is to protect said chamber from the heat when a very hot fire is required.

J is a drip-pan to catch any oilthat may fall from nozzles F F. y

In simplifying my invention for some use I may dispense with the superheating-chamber B and pipe 0 and run the pipe 0 direct from the chamber B to the mixing-chamber E. In such case the nozzle F on the side next to chamber B may be dispensed with.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An oil-burner comprising two steamchambers, one to receive the water and convert it into steam and the other to superheat the steam, both being connected by a pipe and an intermediate mixing and heating chamber for steam and oil placed between the two steam-chambers and connected respectively to an oil-supply pipe and to the superheated steam chamber, and having at its lower part oppositely-directed burner-nozzles pointing toward the two steam-chambers substantially as described.

2.
